Hydrogen like atom with atomic no ' ' is in a higher excited state of quantum no. ' '. This excited state can make a transition to the first excited state by successively emitting two photons of energies respectively. Alternatively the atom from the same excited state can make transition to the excited state by emitting photons of energies respectively. Determine ' '
View answer and explanation
Correct option: A
3
The correct answer is A (3). By equating the total energy difference in both transitions, we can solve for Z.

Which of the following pairs have identical values of e/m?
The correct de Broglie relationship is:
Assertion: Unlike sound waves, electromagnetic waves do not require medium and can move in vacuum.
Reason: The oscillating electric and magnetic fields produced by oscillating charged particles are parallel to each other and both are perpendicular to the direction of propagation of the wave. S-I: The orbital has maximum electron density along the y axis and its nodal plane is xz plane.
S-II : For a given atom, for all values of , the -orbitals have the same shape, but the overall size decreases as '' increases. S-I: Elements like and were discovered when their minerals were analysed by spectroscopic methods.
S-II: The element helium was discovered in the sun by spectroscopic method. In which one of the following, the number of protons is greater than number of neutrons but number of protons is less than the number of electrons?
